In many Asian homes, it's considered good manners to take your shoes off before entering, since shoes can drag in germs from outside the house.

And it's clear one little girl California has learned that lesson all too well from her parents. In fact, she's even passing it on to her Barbies.

Korra Lam, an adorable four-year-old from Orange County, was caught playing by her big half-sister sister, who noticed that the little girl had her dolls take off their high heels and slippers before going inside Barbie's Dream House.

She explained that the little girl made her dolls take off their shoes before they entered the Dream House

So respectful! She included a picture of the shoes nearly lined up outside

Following the rules: Inside, Ken and Barbie were seen lounging barefoot

Korra's 16-year-old sister Ivy Ho stumbled upon the scene this weekend and just had to take pictures to share on Twitter.

'My little sister got a Barbie Dream House N HER ASIAN A** MAKES ALL THE BARBIES TAKE OFF THEIR SHOES BEFORE ENTERING,' she wrote.

In one image, Korra is seen in pajamas, removing a pair of blue T-strap heels from her blonde doll. In another, two Barbies and a Ken doll are seen lounging in the house, barefoot.

Outside the house, the toy shoes are lined up neatly, as they might be on a mat in the entrance-way of a real home.

What a polite little girl: Ivy said Korra told her the dolls took off their shoes to keep the house clean

She listens to her parents:It is common in many Asian homes to take shoes off before entering

Learning fast: Korra went viral for her house manners, gaining hundreds of thousands of likes

'I asked her why, and she said "so they can be like us and keep their house clean,"' Ivy told BuzzFeed. 'I thought it was funny because all my Asian friends do this, but not many of my non-Asian friends do.'

Though she just shared it for her friends to see, the tweet quickly went viral, racking up 385,000 likes and 148,000 retweets.

A few astute Twitter users, though, pointed out that there is actually a doll wearing shoes in the house in one picture. She is sitting on the toilet behind Korra, her feet still in white flats.

Ivy mollified them, though, explaining that the doll was simply waiting her turn for shoe removal and could be seen barefoot in another frame.
